滑动手势从tableView删除文件
if (editingStyle == UITableViewCellEditingStyleDelete){
         NSFileManager *fileManager = [[NSFileManager alloc]init];       
         NSString *filePath = [documentsDirectory
         stringByAppendingPathComponent:[NSString stringWithFormat:@"%@ ",[self->localSongs objectAtIndex:indexPath.row]]];        
        [fileManager removeItemAtPath:filePath error:nil]; 
        [self->localSongs removeObjectAtIndex:indexPath.row];
        [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
        [self.tableView reloadData];
    }

要实现使用滑动手势从TableView删除文件,不从文件目录中

NSString *imageName = @"name of your file"
    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];

    [fileManager removeItemAtPath:[documentsDirectory stringByAppendingPathComponent:imageName] error:nil];
